The temperature got colder by 11 regress
Answer:
14 points
Step-by-step explanation:
The second test Lee did was 13 points fewer than the first test, which was 91 points, so the second test's score is 91 - 13 = 78 points.
The third test had the score of 92, so this is the highest score, and the lowest score is the second one: 78 points.
The difference between Lee's highest and lowest scores is:
92 - 78 = 14 points
You must multiply 5x-3 with 5, then you will get
25x-15 = 1
25x = 1+15
25x = 16
x = 0.64
So we can write
12% of x = 36
12/100 x = 36
x = 36 x 100/ 12
x= 300
So, 300 cookies were ordered in total.
